@Tim Edwards my

cifoutput

and

cifinput

section is defined like this, but once i export a .gds file and try to read it, magic gives error of

Error while reading cell "xxx" (byte position 198): Unknown layer/datatype in boundary, layer=2 type=1

I looked at how the sky130A magic tech file, doesn't look like it's to much different in terms of how

CIF layers

are declared. Am I missing something?

@Anderson Hsieh Can’t be sure without the full file, but I suspect that the

cifinput

section is missing

calma

statements. The

cifinput

and

cifoutput

sections do not share

calma

definitions. In

sky130B

the

calma

statements are near the end of the

cifinput

section.
